Description
Acid denaturation is the process by which proteins lose their tertiary structure due to exposure to acidic conditions, altering texture and flavor.
Technical
Protonation of amino acid side chains disrupts hydrogen bonds and electrostatic interactions, leading to unfolding (e.g., citric acid from lemon juice protonates histidine residues in fish myosin).
Culinary Significance
Used for 'cooking' raw proteins without heat (ceviche), tenderizing meats, and creating silky textures in dairy products.
